<h3>Sentinel-1 Burst Overlap Double Difference Interferogram</h3>

<p>The operator computes the double difference interferogram for
co-registered Sentinel-1 TOPS product for overlapped area between adjacent
bursts.<br>
</p><h4>Input <br>
</h4>



<ul>
<li>The input to this operator should be co-registered Sentinel-1 multi-swath SLC product (e.g. IW product with VH and
VV polarisations). <br>
  </li>
</ul>

<h4>Output <br>
</h4>




<ul>
<li>The output of the operator is the double difference interferogram for all overlapped area between bursts.</li>
  <li>The coherence can also be output for the same area if selected. <br>

  </li>

</ul>


<h4>Parameters Used<br>
</h4>




<ul>
<li>Output Coherence: If this checkbox is selected, coherence band for the overlapped area will be outout.<br>
  </li><li>Coherence Window Size: Dimension of the sliding window for coherence calculation.</li></ul><p><br>
